Tint is measured by the percentage of visible light transmitted through the window, commonly known as the Visible Light Transmission percentage (VLT%). For windshields, tinting can only be applied above the manufacturer’s AS-1 line, located near the top of the windshield. Front side windows must allow a minimum 50 percent passage of visible light. Back side and rear windows must allow a minimum 35 percent passage of visible light.

Proper tinting can have many benefits, such as limiting exposure to harmful UV rays, reducing heat and glare and enhancing privacy. Improper tinting can contribute to reduced vision, both for the operator as well as for other motorists and pedestrians. Following the law will increase the safe travel of motorists and pedestrians and eliminate the possibility of a ticket from police.
